Stanley STGS7125, Manual

2.  Keep the edge of the wheel tilted at angle from 15 to 30 

degrees against the surface of the workpiece.

3.  When using a new grinding wheel, do not operate the 

wheel in the B direction, otherwise, it will cut into the 
workpiece. When the edge of wheel has been rounded 
off, you are free to operate the grinder in either the A or B 
direction.

Starting and Stopping (Fig. 1)

Warning:

 Before using the tool, check whether 

the handle is tightened securely. Check whether 
the ON/OFF switch is working normally.

Before plugging in the tool to the power supply, check 
whether the switch is in the OFF (o) position when pressing 
the rear end of the switch.

To start the tool, press the rear end of the switch and slide it 
forward. Then press the front end of the switch to lock it. 
Press the rear end of the switch to stop the tool.

Warning:

 Do not switch the tool on or off while 

under load conditions.

Proper Hand Position (Fig. 6)

Warning:

 To reduce the risk of serious personal 

injury, ALWAYS use proper hand position as 
shown.

Warning:

 To reduce the risk of serious personal 

injury, ALWAYS hold securely in anticipation of a 

sudden reaction.

Proper hand position requires one hand on the side handle 

(figure 1), with the other hand on the body of the tool, as 

shown in figure 6.

Switches

Caution:

 Hold the body of the tool firmly to 

maintain control of the tool at start up and during 

use and until the wheel or accessory stops 

rotating. Make sure the wheel has come to a 

complete stop be fore laying the tool down.

Note:

 To reduce unexpected tool movement, do not switch 

the tool on or off while under load conditions. Allow the 

grinder to run up to full speed before touching the work 
surface. Lift the tool from the surface before turning the tool 
off. Allow the tool to stop rotating before putting it down.

Slider switch (Fig. 1)

Warning:

 Before connecting the tool to a power supply, be 

sure the slider switch is in the off position by pressing the 
rear part of the switch and releasing. Ensure the slider 
switch is in the off position as described above after any 
interruption in power supply to the tool, such as the 
activation of a ground fault interrupter, throwing of a circuit 
breaker, accidental unplugging, or power failure. If the slider 
switch is locked on when the power is connected, the tool 
will start unexpectedly..

To start the tool, slide the slider switch (a) toward the front of 
the tool. To stop the tool, release the slider switch.For 
continuous operation, slide the switch toward the front of the 
tool and press the forward part of the switch inward. To stop 
the tool while operating in continuous mode, press the rear 
part of the slider switch and release.

Spindle lock (Fig. 1)

The spindle lock (b) prevents the output shaft from rotating 
when attaching or removing the grinding wheel. Only use the 
spindle lock when the tool is switched off, power is 
unplugged, and wheel stops completely.

Note:

 To minimize tool damages, don't use the 

spindle lock when the tool is operating. 
Otherwise, it may damage the tool. The attached 

accessories may come off and cause injury.

If using the spindle lock, press the spindle lock button and 
rotate the output shaft until it stops.

Application on Metals

When applying the tool on metals, make sure that a 
residual-current device (RCD) is inserted to prevent danger 
from metal chips.

If the RCD causes power disconnection, have the tool sent 
to an authorized Stanley dealer for repair.
